JOHN JOSEPH BUKOL'I, OF STEVENS POINT, WISCONSIN.

mtxme-macnmn.

Be itknown that I, J HN J. 1301mm, a citizen of the United Statesresiding at Stevens Point in the county of Portage and StateofWisconsin, have invented certain new and useful Improvements in-Milking- Machines; and I d declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to milking machines,

I and particularly to that type known in the art as hand operatingmachines.

The object of the invention is to provide a machine of this characterwhich may be readily applied, and easily and rapidly operated and whichwill not annoy or injure the animal.

A further object of the invention is a provision of means whereby anequal tension is maintained upon the teats and whereby such tension maybe adjusted for hard or easy milkers, and whereby the machine may beadapted for animals having large or small teats.

A still further object of the invention is a provision of a device ofthis character which may be readily taken apart so that the workingelements of the machine may be eflt'ectually cleaned. v

A still further object of the invention is the provision of means forsupporting the device at any suitable height and for adjusting itsposition at will.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully de-.

scribed and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view showing application ofthe device; Fig. 2 is a side elevation of the device; Fig. 3 is a topplan View; Fig. 4 is an end elevation; Fig. 5 is a transverse sectionthrough the casing; Fig. 6 is a detail perspective view of one type ofroller, and Fig. 7 is asimilar view of a modified form.

Referring more es ecially to the drawings, 1 represents a andle or leverupon which is secured the milking tank or receptacle 2 preferablyconstructed of sheet metal and provided with sides 3 and 4 the latter ofwhich is provided with a hinged top 5 for a preferably constructed of,soft rubber.

purpose which will be hereinafter described. hese sides are connectedbyend members 6 which have their edges adjacent the sides 3 rovided withnotches 7 to be hereinafter reerred to. The end members are preferablyprovided with vertical or-substantiall vertical slots 8 which connect attheir en with slots 9- adapted to receive and form a hear ing for theshaft 10 of the milking rollers 11. This shaft is held against suitablebufiers 12 carried by the end members by bearing elements 13 pivoted attheir lower ends 14 to the ends of the casing 6 and p'rovided adjacenttheir upper ends with notches 15 adapted to receive the shaft 10.Suitable springs 16 are connected to the bearing elemen s 13intermediate their engagement with the shaft and their pivotal point soas to draw the bearing elements against the shaft and force the latterinto engagement with its limiting buffers. The opposite ends of thesesprings are' connected to a suitable rod 17 which extends from end toend of the casing and projects therebeyond to be attached to thesprings, which hold the rod in engagement with the notches 7. It will beseen that by adjusting the rod the tension of the springs may be changedto suit the working end. The end of the shaft 10 projects beond the endof the casing and 1s provided with a clutch element or collar 18 notchedat 19 to receive a cross pin connected to the operating shaft 20. Thisoperating shaft 20 is mounted in a bearing 21, and is provided at theend opposite from the clutch with a beveled gear 22 adapted to beengaged by a similar gear 23 carried upon the crank shaft 24. This crankshaft together w ith the gear 22 and the operating handle is mountedupon an adjustable bracket 26 held in adjusted position upon the handle1 by means of the thumb screw 27 which passes through the handle andthrough a slot 28 in the bottom of the bracket. By this means it willreadily be seen how the shaft 20 may be disconnected from the shaft 10,and it will be seen how the milking rollers may then be disconnectedfrom their bearing elements and removed from the casing through theslots 8. The milking rollers are preferably arranged as shown in Figs. 6and 7, in the former ofwhich they are arranged upon brackets 29'carriedby the shaft 10 and alre n rest which wi ing rod 35 hel Fig. 7 brackets30 and 31 are provided which are arranged at right an les to each otherso that the teat on the leg hand side of the udder receives a strokeintermediate the restingperiod of the teat on the right hand side of theudder. In the structure shown in Fig.

6 both teats on the right and left hand sides of the udder are operatedsimultaneously. A suitable nipple or outlet tube 32 is connected to theottom of the casing at the inner end and is so'constructed that a pieceof rubber. tubing may be slipped thereover to conduct the milk from themilking pail. In order that there may be no damage or injury done to theanimal, I preferably provide a soft rubber pad 33 which extends the fulldepth or approximately the full depth of what may be termed the milkingside of the casing 3, so thatthe teat lies against said pad and ispressed thereagainst b which it will e seen, conform to the are on whichthe side of the casing is made.

In order to support the device in operative position, I preferablyprovide a standard 34 in which is reci rocally mounted a sup ortd inadjusted position by a thumb. screw 36. This supporting rod is pivotallyconnected to a thumb bolt 37 which is carried b the handle 1. It willreadily be seen how this standard may be substituted for a clamp to beadapted for attachment on the milking ail or substituted for a knee 1have the rod 35 mounted adjustably therein.

In operation the device is supported on the standard in properlyadjusted position, the forward and rear tents of the udder placed in thecasing against the soft rubber pad 33. The handle is then revolved in aright hand direction which turns the shaft 10 through the shaft 20 andthe gear 22, in a left hand direction, thus bringing one of the rollers11 in engagement with the teats and forcing out the milk containedtherein. After the roller leaves the teats the interval between thefirst operation and the succeeding engagement by the second rollerpermits the teats to fill again, and the operation is thus, repeated. Itwill be noticed that the casing end of the handle should be slightlyelevated in practice so that the milk in the trough formed in the bottomof the casing will gravitate to the spout 32 and from thence into thebucket through the customary rubber tube.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advancasing to the I the rollers 11in theirtravel with the limiting means,

. operate said rollers tages of this invention as defined in the uppended claims.

Having thus described and ascertained the nature of my invention, what Iclaim as new and desire to secure by Letters-Patent, is p 1-. In adevice of the class described, a milk ng machine, a manipulating handleextendm therefrom, and a supporting fulcrum or'the machine pivoted tothe handle intermediate its length.
